Abstract

The authors present a mathematical model that can
be used to model the electromagnetic (EM) fields generated by
a vertically oriented magnetic dipole (VMD) located above a
conductive half-space, such as biological tissue. The model was
compared to a full-wave simulation in CST. The difference is
shown to be below 8.1% on average for frequencies ranging
from 13 MHz to 5 GHz. It executes over 800 times faster than
a full-wave solver, using more than 20 times less memory, and
can be adapted to model more realistic magnetic sources without
much extra effort. This model can improve the design process of
inductive or radiative links significantly, enabling rapid design
iteration. It is well suited for biomedical applications. Extension
to magnetic sources with arbitrary orientation, as well as electric
sources, is possible.
